Question

Whats an explicit rule for this? 14, 20, 26, 32, etc. Write an explicit formula for the nth term an.

Answer 1

a(n)=14+6(n-1)

Explanation:

The first term is 14. This would be an arithmetic sequence, so you will add 6 to every term: the common difference is 6.

14+6= 20

20+6=26

You have the formula a(n)= a(1)+d(n-1)

a(n)= 14+6(n-1)

14 for the first term, 6 for the common difference.
